Defined terms used in this announcement shall have the same meaning as those terms defined and used in the prospectus of the Company dated 6 July 2012.

The Company has received valid acceptances in respect of 23,362,652 Open Offer Shares from Qualifying Shareholders. This represents approximately 11.6 per cent. of the Open Offer Shares offered. All eligible applications received from Qualifying Shareholders will be allocated their pre-emption entitlements and all eligible applications under the Excess Application Facility will be allocated their Open Offer Shares as applied for.
